Replacing the Battery
Replace the lithium ion battery pack when its life becomes
noticeably shorter. The battery is normally good for up to
400 charge/discharge cycles.
An internal lithium battery maintains the tester’s clock and
other settings when you remove the battery pack. This
battery typically lasts about 5 years. When the battery

To avoid damaging the display or the case, do not
use solvents or abrasive cleansers.
Before storing the tester or an extra battery for an
extended period, charge the battery to between
70 % and 90 % of full charge (2 or 3 LEDs lit on the
battery’s gauge). Check the battery every 4 months and
recharge if necessary.
Keep a battery attached to the tester during storage.
Removing the battery for long periods shortens the life
of the lithium battery that maintains the clock.
